INTERNAL-COMBUSTION IIVIIO'JTOR.

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed February 18, 1901. Serial No. 47,893.

To all whom 'it may concern:

Be it known that I, CLYDE J. COLEMAN, a citizen of the United States, and a resident of the borough of Manhattan, in the county of New York, city of New York,

and State of New York, have invented new and useful Improvements in Internal-Combustion Motors, of which the following is a specification, reference being had to the accompanying drawings, forming partthereof.

My invention relates tointernal combustion motors and particularly to internal combustion motors designed to operate at a very high speed.

My invention consists in the provision of a compound compressor connected with an internal combustion motor whereby a high degree of compression of the motive fluid may be attained with a minimum expenditure of power in effecting such compression; in the provision of a storage tank for receiving and storing a reserve supply of compressed motive fluid, together with means whereby such motive fluid may be employed in the motor when desired; in providing the motor with a rotary and a stationary member having turbine blades,

' the rotary member being exteriorly arranged; in providing the two members with two sets of turbine, blades and a combustion chamber between them; and in compounding these sets of turbine blades on both sides of the combustion chamber. The objects of my invention are to provide for the rapid and continuous compression of a large quantity of motive fluid in order that a high speed may be attained in the motor, and hence a high degree of efliciency obtained therefrom, while at the same time to provide that a minimum of power may be expended for effecting the compression; to provide an auxiliary or reserve supply of compressed motive fluid to be employed in first starting up the motor; to increase the efficiency of the motor while reducing its size and weight; to maintain a low temperature in the rotary member so that it may resist the great centrifugal force; and to balance the operation of the.

motor, wherebysteadiness of working and greater speed with proportionately less vibration are obtained.

My invention further consists in certain details of construction and combination of parts as will hereinafter more fully appear,

and other advantages will be ap arent from the more detailed description following. I will now proceed to describe an internal combustion motor embodying my invention and will then point out the novel features in claims. v

In the drawings which form a part of this specification; Figure 1 is a central longitudinal sectional elevation of an internal combustion motor embodying my invention. Fig. 2, is a central transverse sectional view of the same, the plane of section being taken on the line 22 of Fig. 1. Fig. 3, is a-detail transverse sectional view taken upon the plane of the line 3-3 of Fig. 1. Fig. 4, is a detail view in side elevation of one member of the motor.

In the present embodiment of my invention I-provide a base plate 1 having standards 2 which support the opposite ends of a stationary shaft 3.

Itotatably supported upon the stationary shaft is a rotary compound compressor 4. The said compressor has a plurality of comcompression chambers 5, and inner compression chambers 6 of smaller diameter, and a plurality of compound reciprocating pistons for the cylinder, having heads 7 fitting the chambers 5 and smaller heads 8, fitting the chambers 6. The pistons are connected by means of connecting rods 9 with a stationary wrist pin 10, supported by crank armscon- .necting to, or a part of, the stationary shaft 3.

When the compressor 4 rotates upon the stationary shaft 3 the pistons are caused to reciprocate and motive fluid is initially compressed in the outer chambers 5 of the cylinders and discharged from thence into the inner chambers 6. The motive fluid is further compressed in the inner chambers and is then discharged into the central chamber 11 of the compressor, from whence it is delivered through a hollow portion of the stationary shaft into the combustion chamber of the motor. Motive fluid is delivered to the outer chambers 5 of the compressor cylinders through pipes or conduits 12 which connect with a receiving chamber 13, this receiving chamber being in direct communication with a carbureter 14.

The motor proper comprises two members, a stationary and a rotary member. The stationary member 15 is secured upon the stationary shaft 3 and is provided with'two sets of directing vanes 16 radiating out- ,ivardly therefrom, and arranged upon opposite sides of a central combustion chamber 17, The rotary member 18 is secured at one end to the compressor and at the other end is rotatably mounted upon the stationary shaft, and is arranged exteriorly to the stationary member. This rotary member is provided with a plurality of radial turbine vanes 19, projecting inwardly, and arranged in proximity to the directing vanes of the stationary member 15..

At the center of the combustion chamber 17 is .provided a burner 20. The burner consists of a number of apertures provided radially around the hub of, the stationary member, and communicating through the hollow portion of the shaft awah the central chamber 11 of the compressor. Wire gauze is provided back of the apertures to prevent a possible back flashing of the flame from the combustion chamber into the interior of the burner.

The turbine vanes being arranged upon opposite sides of the central burner and-combustion chamber, a balance of force and an equal distribution of power is insured. The vanes are further compounded, that is to say there are arranged on opposite sides of the combustion chamber successive rows of Jturbine impact vanes alternating with sucof motive fluid to the motor.

cessive rows of turbine directing vanes.

In this manner a high degree of elficiency is obtained.

It is my intention to operate the motor herein at a high'rate of speed in order to obtain a high degree of efiiciency. In order that it shall run at a high rate of speed it is necessary to continuously compress a large quantity of motive fluid to a high degree so as to deliver a suflicient quantity To this end a compound--com ressor is employed for the reason that a iigher degree of efliciency combined with small dimensions and weight of the parts and the use of a smaller amount of power is possible in a compressor of such type. With the compressor connected to rotate with the rotary member of themotor, it is essential that the parts should be small and light, otherwise centrifugal force would be liable to be generated to an unsafe extent, and vibration and wear would be excessive. If motive. fluid is employed at a high pressure and a motor having turbine vanes is employed, it is essential to economical and efficient operation that the vanes should be compounded, otherwise the motive fluid would be forced throu h the vanes without producing the most' e ective results, and a large percentage of its energy would be wasted. Hence I employ a compound compressor combmed with a turbine motor having compound vanesand by such combination obtain an internal combustion motor of small size and exceedingly high efliciency.

In order to obtain a supply of compressed motive fluid when starting up the motor, I provide a storage tank 21 which is connected to the central chamber 11 of the compressor through a pipe-or conduit 22 and a hollow portion of the stationary shaft 3. While the compressor is working, motive fluid will be stored up in this storage-tank under pressure, and will be retained therein by a check compressed fluid from returning along the pipe 22 until desired. Motive fluid is thus stored up under pressure which may be the pressure has run down therein, for the purpose of starting the motor up again. In order to use the compressed and stored motive fluid for such purpose I have provided a by-pass 24 around the check valve, and have provided therein a valve 25 which may be operated by hand or otherwise to permit the stored motive fluid from the tank 21 to discharge into the motor. The tank is designed to store a suflicient quantity to start the rotation of the motor and to operate it until the compressor provides the normal and constantsupply. During the operation of the motor the tank 21 will be recharged and the valve 25 may be closed at once or it may be closed at any time after the compressor hascommenced to supply motive fluid at a pressure greater than the pressure in the tank at that time, and before the motor has been again stopped.

mediately the motor hascommenced to run at full speed and pressure. I

It is evident that various changes and modifications may be made in the construc tion shown and above particularly described within the spirit and scope of my invention.
